Question

How much heat (in joules) is used to heat a 79.00 gram sample of iron from 0.580 degrees Celcius to 100.00 degrees Celcius if the specific heat of Fe is 0.450 ^J/_g°C?

Answer 1

To find the amount of heat (q) used to heat the Fe sample, use the equation q=(m)(c)(delta T):

q=(m)(c)(delta T)

q=(79.00g)(0.450J/g°C)(100.00°C-0.580°C)

q=(35.55J/°C)(99.42°C)

q=3534.38J
